This reverts commit 21641a2f6d.
It was causing the following test failures:
lldb-Suite.lang/objc/objc-class-method.TestObjCClassMethod.py
lldb-Suite.lang/objc/foundation.TestObjCMethodsString.py
lldb-Suite.lang/objc/foundation.TestConstStrings.py
lldb-Suite.lang/objc/radar-9691614.TestObjCMethodReturningBOOL.py
lldb-Suite.lang/objc/foundation.TestObjCMethodsNSArray.py

We never compare these directories (where ConstString would be good) and
essentially just convert this back to a normal string in the end. So we might
as well just use std::string. Also makes it easier to unittest this code
(which was the main motivation for this change).
llvm-svn: 371623
LLVMUserExpression doesn't use these variables and they are all specific to Clang.
Also removes m_const_object as this was actually never used by anyone (and Clang
didn't report it as we assigned it in the constructor which seems to count as use).
llvm-svn: 370440
This reverts commit r367842 since it wasn't quite as NFC as advertised
and broke Swift support. See https://reviews.llvm.org/D46083 for the
rationale behind the original functionality.

Summary:
This removes DeclVendor's dependency on clang (and ClangASTContext).
DeclVendor has no need to know about specific TypeSystems.

llvm-svn: 369735
Summary:
This introduces a layer between DeclVendor and the currently implemented
DeclVendors (ClangModulesDeclVendor and AppleObjCDeclVendor). This
allows the removal of DeclVendor::GetImporterSource which is extremely
clang-specific, freeing up the interface to be more general.
A good follow up to this would be to remove the remaining instances of
clang in DeclVendor, either by moving things to ClangDeclVendor or by
using wrappers (e.g. CompilerDecl instead of clang::NamedDecl).

Now that we've moved to C++14, we no longer need the llvm::make_unique
implementation from STLExtras.h. This patch is a mechanical replacement
of (hopefully) all the llvm::make_unique instances across the monorepo.

It seems this breaks the following tests:
lldb-Suite :: expression_command/call-function/TestCallUserDefinedFunction.py
lldb-Suite :: expression_command/rdar42038760/TestScalarURem.py
Let's revert this patch and wait until we find an actual issue that could be
fixed by also doing the guard variable check on Windows.
llvm-svn: 368920
The isGuardVariableSymbol option for ignoring Microsoft's ABI
was originally added to get the bots green, but now that we found
the actual issue (that we checked for prefix instead of suffix
in the MS ABI check), we should be able to properly implement
the guard variable check without any strange Microsoft exceptions.
llvm-svn: 368802
Summary:
Ideally CompilerType would have no knowledge of clang or any individual
TypeSystem. Decoupling clang is relatively straightforward.
Differential Revision: https://reviews.llvm.org/D66102
llvm-svn: 368741
It seems the broken guard variable check for Windows was a feature(TM)
and not a bug, so let's keep add a flag to the guard check that keeps
the old behavior in the places where we ignored guard variables before.

Summary:
And not `zero`. This is the last API needed to be converted to
an Optional<T>.

Summary:
Our IR rewriting infrastructure currently fails when it encounters a variable which has no metadata associated.
This causes dynamic_cast to fail as in this case IRForTarget considers the type info pointers ('@_ZTI...') to be
variables without associated metadata. As there are no variables for these internal variables, this is actually
not an error and dynamic_cast would work fine if we didn't throw this error.
This patch fixes this by removing this diagnostics code. In case we would actually hit a variable that has no
metadata (but is supposed to have), we still have the error in the expression log so this shouldn't make it
harder to diagnose any missing metadata errors.
This patch should fix dynamic_cast and also adds a bunch of test coverage to that language feature.

Not NFC as this will probably fix a wrong guard variable check
on Windows. Not sure though what Windows test can now be safely
enabled.

Summary:
After rL368069 I noticed that HAVE_SYS_TYPES_H is not defined in
Platform.h, or anywhere else in lldb. This change fixes that.

After the recent refactorings the SymbolVendor passthrough no longer
serve any purpose. This patch removes those methods, and updates all
callsites to go to the symbol file directly -- in most cases that just
means calling GetSymbolFile()->foo() instead of
GetSymbolVendor()->foo().
llvm-svn: 368001
The UpdateLanguageForExpr should only update the language, but over
time it started to do also do different things related to the generation
of the expression source code. This patch refactors all the source code
generation part into its own function.
llvm-svn: 367922
Currently Target::m_next_persistent_variable_index is counting up
for our persistent variables ($0, $1, ...) but we also have a
unused counter that is supposed to do this in
ClangPersistentVariables but that stays always at 0 (because
we currently increase the target counter when we should increase
that unused counter).
This patch removes the counter in Target and lets the documented
counter in ClangPersistentVariables do the variable counting.
Patch *should* be NFC, but it might unexpectedly bring LLDB to
new code paths that could contain exciting new bugs to fix.
llvm-svn: 367842
Summary:
Currently, clang's FileManager uses NULL as an indicator that a particular file
did not exist, but would not propagate errors like permission issues. Instead,
teach FileManager to use llvm::ErrorOr internally and return rich errors for
failures.

Summary:
This commit achieves the following:
- Functions used to return a `TypeSystem *` return an
`llvm::Expected<TypeSystem *>` now. This means that the result of a call
is always checked, forcing clients to move more carefully.
- `TypeSystemMap::GetTypeSystemForLanguage` will either return an Error or a
non-null pointer to a TypeSystem.

Instead of passing the FileCollector around as a reference or raw
pointer, use a shared_ptr. This change's motivation is twofold. First it
adds compatibility for the newly added `FileCollectorFileSystem`.
Secondly, it addresses a lifetime issue we only see when LLDB is used
from Xcode, where a reference to the FileCollector outlives the
reproducer instance.
llvm-svn: 367258
The FileCollector got lifted into LLVM and a shim was introduced in LLDB
to keep the old API that takes FileSpecs. This patch removes that shim
and converts the arguments in place.
llvm-svn: 366975
This patch changes the coding style of the FileCollector from the LLDB
to the LLVM coding style. Alex recently lifted it into LLVM and I
volunteered to do the conversion.

This patch replaces explicit calls to log::Printf with the new LLDB_LOGF
macro. The macro is similar to LLDB_LOG but supports printf-style format
strings, instead of formatv-style format strings.
So instead of writing:
if (log)
log->Printf("%s\n", str);
You'd write:
LLDB_LOG(log, "%s\n", str);
This change was done mechanically with the command below. I replaced the
spurious if-checks with vim, since I know how to do multi-line
replacements with it.
find . -type f -name '*.cpp' -exec \
sed -i '' -E 's/log->Printf\(/LLDB_LOGF\(log, /g' "{}" +
